In many cases the pit also has a groundwater drain systesm connected to it. If yours does then that is the source of the water running into the pit. The bigger concern would be where the water is coming from initially. If it is just normal drainage that is okay, but if it is a broken sewer or water pipe then you would have to locate it and fix it.

: I have an ejector pit that will sometimes kick on every 10 minutes. This seems to happen after a strong storm, although not always. The only things draining into the pit are the A/C, the utility sink, and the washer. After observing the pit more closely, I have noticed that even after it kicks on, I hear water draining/running? inside the pit? Not sure where this water is coming from, but it seems to cause the pump to run so frequently - 24/7! Of course, the washer and utility sink are not draining, and the A/C drains only slightly when this is happening. At times, the A/C is even off, so nothing is draining into the pit. Help.
